CAR-TRUCK.

ernerrrcnrrion forming part of Letters Patent No. 650,128, dated May 22, 1900.

Application filed July 22, 1899. Serial No. 724,887. (No model.)

To' all whom, t may concern:

Be it known that I, HENRY S. GOUGHNOUR, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Improvement in Car-Trucks, of which the following is a full, clear, and exact description, reference being had to the accompanying'drawings, which form a part of this specification.

My invention has relation to an improved bolster-fastening fo'r car-trucks and is de signed to provide means of simple character for. connecting a vehicle-body to a bolster to be used in lieu of the king-pin and swivelplate connections usually employed and whichis designed to facilitate the ready conneetion and disconnection of the car body and 'ing on the line x a: of Fig. l.

truck. I attain this object by the means now to be described and hereinafter more particularlypointed ont, reference being had to the accompanying'drawings, in which- Figure l is an endclevation, partly in section, of so much of a car body and truck as is necessary to illustratemy invention. Fig. 2 is a vertical section of my improved fasten- Fig. 3 is a detail plan view, and Fig. 4 is a section on the line y fz/ of Fig. 3.

In the drawings the letter A designates a car-body, -and.B a double truck, which in general maybe of any of the various types known to the art. The truck .which I have shown has a rigid bolster consisting of parallel bars b h, spring-supported on the transverse members Br of the truck-frame.

, C designates a solid block or casting which is securely fastened between the bolster-bars b at the center of the. truck in the place of the usual king-bolt socket and lower swivelplate. This block or casting is formed on the upper face witha boss or projection C', cored out to form a cylindrical socket C2. At the bottom of the socket there is preferably provided a hemispherical bearing projection c, elevated above the bottom of the socket to a considerable extent, the surrounding space constituting in use an oil or lubricant chamber. Formed in the lateral wall of the socket above the said projection is an annular groove c2.

'D designates a casting or forging which is securely bolted to the under side of the carbody above and directly over the block or casting C and which is provided with a depending cylindric stud or post D', adapted to enter the socket of the said block or casting and form a neat bearing iit therein. The lower end of this stud or-post is hollowed out, as indicated at (I, to fit the projection c, and its lower end portion is provided with an an nular groove d', which registers with the groove c2 when the parts are applied to each other, as shown, the connection between said post and socket for preventing vertical separation being made by one or more cylindrical pins F, inserted into the closed annular space formed by said registering grooves.

The means .above described form, as will be readily seen, a simple yet secure and eiicient connection between the car body and truck, possessing perfect lateral rigidity, while it affords freedom of -rotary movement and extended bearing-surfaces. To permit the body to be removed from the truck, itis only necessary to withdraw the pins F, when the parts may be readily separated from each other'.

The lower portion of `the block or casting. C is shaped to have a central bearing and support on the bolster-truss G.

The connection described can be readily adapted to other forms of trucks and holsters without departingl from the scope of the invention and may also be otherwise changed in its. details of construction and arrangement, to which therefore I do not desire to limit myself.

Having thus described my invention, what I claim, and desire to protect by Letters Patent, is--vn 1. The herein-described bolster-fastening, comprising a member rigidly secured to the bolster and formed with acylindrical vertical socket whose bottom wall has a convex bearing projection and a surrounding oil-space, and a member rigidly secured to the under side of the ear-body and carrying a depending post adapted for rotary engagement with said socket and concaved on its lower face t0 fit said projection, together with means for preventing vertical separation of said members. 4

2. The combination with a member secured I socket member and the post or stud while it permits rotary movement of the latter.

3. In a. car-truck, the combination with acar-body provided with a depending bearing post or stnd, of a car-truck ,having ablock secured between the bolster-bars and formed with a socket to receive the said post or stud, and means for securin g said stud against Vertical movementin said socket without interfering Withits'rotary movement, said block Aai: its lower end also having a bearingon the bolster-truss.

In testimony` whereof I have affixed mysignature in presence of-two witnesses.
